Question: plasma membrane
Answer:
The membrane at the boundary of every cell that acts as a selective barrier, thereby
regulating the cell's chemical composition.
Question: Ribosomes
Answer:
complexes that make proteins; free in cytosol or bound to rough ER or nuclear envelope
Question: Golgi apparatus
Answer:
active in synthesis, modification, sorting, and secretion of cell products
Question: Lysosome
Answer:
digestive organelle where macromolecules are hydrolyzed, and autophagy
Question: Mitachondrion
Answer:
organelle where cellular respiration occurs and most ATP is generated
